What are the protective effects and industry standards of box type transformer guardrail?

In neighborhoods or roadsides, you will often see the perimeter of box substations separated by fences. If you look carefully, you will find that box type transformer guardrail and transformer box usually keep a certain distance, the height of the transformer box basically maintain a certain proportion of the height. Outdoor box type variable fence is available in a variety of specifications. Outdoor box type variable fence not only provides isolation, but also separates the crowd from the high voltage transformer box, reducing the occurrence of some dangerous accidents, and allows the box to change freely. Destruction also increases the aesthetic effect of urban landscape to a certain extent.

First, we must understand box substations.

Box substation, also known as prefabricated substation or prefabricated substation

It is a high voltage switchgear, distribution transformer and low voltage distribution device. It is integrated into factory prefabricated indoor and outdoor compact power distribution units according to a certain wiring scheme. It is a combination of transformer step-down and low voltage distribution functions. It is installed in the steel structure box, moisture-proof, rust-proof, dust-proof, rat-proof, fireproof, anti-theft, heat insulation, fully enclosed, removable. Applicable to urban network construction and reconstruction.

Therefore, the role of outdoor transformer guardrail is summarized as follows:

1. Keep a safe distance between the crowd and the box-type substation to prevent leakage and other situations.

2. isolation, to a certain extent to prevent damage to the outdoor box variable fence and climbing.Another important point is to avoid affecting the appearance of the city. It can be used to separate the work areas of different sites, effectively improve the environment and correct planning.

With a huge box standing inside, it will feel a bit awkward, and the outdoor box will become a fence, which will make the space look more layered and comfortable.

Specification for outdoor transformer guardrail:

1. The height of the transformer installed on the ground is 0.5 meters; The surrounding area should not be less than 1 meter; There should be a distance of more than 2 meters in the direction of operation.

2. The bottom of transformers 315KVA and below should be no less than 2.5 meters above the ground, which can be installed on the rod.

3. The rod on the rod should be stable and firm, and the waist rod should be wrapped with more than 4 turns of iron wire, with a diameter of 4.0mm; The wire should not have joints and the waist should not be less than 0.2m.

4. The height of the transformer installed on the ground is generally 0.5 meters. There should be a fence of not less than 1.7 metres around and warning signs should be hung in visible places.

5. There are corresponding regulations on the proportion of outdoor box variable fence and transformer overall structure.

In fact, outdoor box variable fences do more than that. Nowadays, many cities are pressurizing cities with pressure boxes. The combination of fences and graffiti makes the image more layered, like a frame, landscape. Therefore, outdoor box variable guardrail not only ensures our daily safety, but also plays an irreplaceable role in urban beautification.
